UNITED STATES PATENT OFFICE.

CHARLES P. WHITNEY, OF MILFORD, NEW HAMPSHIRE.

FOLDING UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 274,687, dated March27, 1883.

Application filed August 2, was. (no model.)

To all whom it may concern: I

Be it known that I, CHARLES P. WBITNEY, a citizen of theUnited States ofNorth America, and a resident of Milford, county of Hillsborough, Stateof New Hampshire, have invented a new and useful Improvement in FoldingUmbrellas, of which the following is a specifiexhibit other parts of aportion of the handle,

showing different views of my improved joint or jointing devicetherefor.

- section on line w m, Fig. 1, looking upward.

5o shoulders t at the four corners.

Fig. 4is across-section online y y, Fig. 1, looking downward. Fig. 5 isa partly-sectional elevation, showing my improved rib-jointing device.Fig. 6 is a side elevation, showing the position of parts when thehandle-sections are nearly folded together.

Similar letters of reference indicate corresponding parts. Y r

A represents the central section of the umbrella-handle; B the uppersection, and O the lower section, thereof.

The sections A B are united by means of a jointing device, D, whichconsists of a tube, a, secured on the upper end of section A, andforming part thereof, and having internal shoulders, b, formed at itsupper end. The opening about which the shoulders b are formed isdesigned to be squared or rectangular, corresponding to shape of the barD, whose upper end is secured by pivot h in the link D while the upperend of the latter is held by pivot r to the lower end of the round bar Dthe upper end of the latter being screwedor otherwise rigidly secured ina ferrule, k, on the handle-section B. Bar D is round, with an upper endof square cross-section, thus forming A pin, a, projecting from thesides of the bar D and rest- Fig. 3 is a crossing on the shouldersb,prevents the detachment of one handle-section from the other. D is cutaway at w' to form a recess, which will receive the edge of the socketwhen the umbrella is folded, and thus the parts will lie closertogether, as shown in'Fig. 6.

In the base of the socket formed by the tube a is secured a spiralspringmn, whose'other end is made fast to the lower end of the barv D,and assists by its tension in drawing the 'be pushed upward until it isin contact with section B, and the shoulders 15 on the bar D thencomingabove the internal shoulders, I), a slight or partial turn of thesection A will bring the shoulders it across the internal shoulders, b,whereby the handle-sections A B are held straight, and. firmly in linewith each other, and the action of the spring m at the same time tendsto prevent the accidental returning of the handle-section A.

The handle-section C is preferably provided with ascrew, as shown at n,and can be there by screwed.into the lower end of the section 0, and bereadily detached therefrom when desired, and said sections A O arepreferably united with a joint, 7c.

The umbrella-ribs]? are jointed, as shown at 0, at about midway of theirlength, so that their lower portions may be turned back or foldedupward, and they are provided with short metallic re-enforcin g pieces gabout their jointed ends, and over .and upon each rib F is a slidingsleeve, G, that is pivoted, as shown at s, at its upper end to thestretcher H. The

runner I differs from the ordinary umbrella- .runncr in having thenotch-wheel o near the the'ribs F are straightened or unfolded, and

This bar rib-joints 0, and the sleeve-sprin gs p, pressing against thejointed rib ends, serve to hold the sleeves G in their position whileopening the umbrella, and tend greatly to increase the rigidity andstiffness of the joints and to prevent any undue freedom of movement ofthe lower ends of the umbrella-ribs.

-I do not broadly claim a folding umbrella, as I am aware that othershave been made with one or two joints in the handle, but,

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a folding umbrella, the handlehaving ajoint atD, combined with ribs havingjoints which, when folded,will lie adjacent to the joint D in the handle, and with a runner andstretchers carrying sleeves which embrace and cover the hinged ends andpivots of the ribs, whereby the cover is protected from the wear causedby the hinges and the rib-joints are supported when the umbrella isopened, as set forth.

2. The combination, with thejoint D, of the spring m, having one endconnected to the bottom'ot' the socket a. and the other end to the jointby a pin, 0, such pin also serving as a stop for the joint 1) againstthe flanges b, as set forth.

3. In a folding umbrella, the combination, with thehandle-sections,ofthe jointing device D, consisting of tube a, provided with internalshoulders, 1), bars D D the latter having shoulders t, pivoted link Dand. spring m, constructed, arranged, and adapted to operatesubstantially as herein shown and described.

4.- In a folding umbrella, the combination, with the jointed ribs F andstretchers H, of the sliding sleeves G, attached to said stretchers, andprovided with internal springs,p, substantially as and for the purposedescribed.

5. In a folding umbrella, the combination of the ribs F, jointed at 0,and having re-enforcing pieces 9, the stretchers H, and the runner I,with the sleeves G, having springs 9, as and for the purposes specified.

6. In a folding umbrella, the combination, with the jointed ribs F,provided with menforcing pieces gand stretcher-attached sleeves G, ofthe pivotss, substantially as herein shown and described, whereby saidsleeves are prevented from sliding too far on the said ribs, as setforth.

7. In a folding umbrella, the combination of the handle-sections A B O,jointed at D and K, substantially as described, and the ribs F, hingedat 0, and having re-enforcing pieces g, with the runner I, stretchers'H,and sleeves G, having springs 19, as and for the purposes set forth.

8. In a folding umbrella, and in combination with the jointed handle,the rectangular bar D, having recesses w, adapted to receive the edge ofthe socket a, and to serve as and for the purposes specified.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 24th day of July, 1882.
